SMBJ26A

The SMBJ26A is a type of transient voltage suppressor (TVS) diode manufactured by FTR (Fujitsu Component Limited). It is designed to protect sensitive electronic components from voltage spikes and transients, which can occur due to various factors such as lightning strikes, electrostatic discharge (ESD), or switching surges.

Key Features and Specifications:

1. Voltage Rating: The SMBJ26A has a breakdown voltage of approximately 26 volts, making it suitable for applications where the operating voltage is around this level. It is designed to clamp voltage spikes effectively while allowing normal operation of the circuit.

2. Power Dissipation: The device can handle a peak power dissipation of up to 600 watts for a short duration, which is crucial for absorbing high-energy transients without failing.

3. Package Type: The SMBJ26A is housed in a DO-214AA (SMB) package, which is a surface-mount device (SMD) configuration. This package is compact, allowing for easy integration into various circuit designs while providing good thermal performance.

4. Response Time: The SMBJ26A features a fast response time, typically in the nanosecond range, ensuring that it can react quickly to voltage spikes and protect downstream components.

5. Clamping Voltage: The clamping voltage is specified at a certain peak pulse current, which indicates the maximum voltage the device will allow during a transient event. This is critical for ensuring that sensitive components are not exposed to damaging voltages.

6. Operating Temperature Range: The SMBJ26A is designed to operate within a wide temperature range, typically from -55°C to +150°C, making it suitable for various environmental conditions.

7. Applications: This TVS diode is commonly used in automotive electronics, telecommunications, consumer electronics, and industrial applications where overvoltage protection is essential. It can be found in power supplies, data lines, and signal lines.

8. Construction: The SMBJ26A is constructed using a silicon-based material, which provides reliable performance and stability over time. Its design ensures minimal leakage current during normal operation, which is important for maintaining circuit efficiency.

Summary:

The SMBJ26A from FTR is a robust and reliable transient voltage suppressor diode that offers effective protection against voltage transients in a compact package. Its specifications make it suitable for a wide range of applications, ensuring that sensitive electronic components remain safe from potentially damaging voltage spikes.
